The Home Owners’ Loan Corporation was a temporary federal agency created on June 13, 1933, to stop the wave of Depression-era foreclosures by refinancing distressed home loans on terms families could actually pay. During its three-year lending window, it took over more than a million mortgages worth roughly $3.1 billion, replaced short-term balloon loans with long-term amortized ones, and in the process produced the color-coded “Residential Security” maps that gave the country its lasting template for redlining.
Why Congress Created It
By 1933, roughly a thousand American homes were being foreclosed every day. Unemployment sat near 25 percent, and home values in many cities had fallen by half or more. The mortgage of the era made the collapse worse: a typical loan ran five to ten years, required a down payment of about 35 percent, and ended in a balloon payment. When the note came due, the borrower either paid the full remaining balance or found a new lender. In a shrinking economy, neither was possible for millions of families.
The Home Owners’ Loan Act, signed by President Roosevelt on June 13, 1933, created HOLC as an emergency agency capitalized with $200 million from the Treasury and authorized to issue up to $2 billion in bonds. Congress later raised that ceiling to $4.75 billion. The plan was simple: buy the bad mortgages off the lenders, then rewrite them for the homeowners.
How the Refinancing Worked
HOLC’s mechanism was a swap. A bank holding a delinquent mortgage could trade it to the government for HOLC bonds worth up to 80 percent of the property’s appraised value. The bonds ran 18 years and paid 4 percent interest. At first, only the interest carried a federal guarantee, not the principal, which made lenders reluctant to accept the trade; Congress extended the guarantee to cover principal as well in 1934.1United States Government Publishing Office.

Once the lender accepted, the old mortgage disappeared. In its place the homeowner got a fully amortized 15-year loan at 5 percent interest, later reduced to 4.5 percent. Monthly payments came to about $7.91 per $1,000 borrowed. That was manageable for most families when the alternative was losing the house, and it was the first widespread use of the long-term self-amortizing structure Americans now take for granted.
Who Qualified
The statute drew hard lines. A borrower had to be in involuntary default as of June 13, 1933, or show that a later default came from unemployment or hardship beyond their control. They also had to demonstrate that no private lender would refinance them. HOLC was a last resort, not an alternative source of credit.2Library of Congress.

The property had to meet three tests. It had to be a dwelling for four families or fewer, ruling out commercial buildings, larger apartment houses, and farms. The owner had to live in it or hold it as a homestead, ruling out vacation homes and speculative holdings. And the property’s value could not exceed $20,000, with the maximum loan on any single home capped at $14,000.2Library of Congress.

Those limits pointed the program at small-scale urban and suburban homeowners in the lower and middle economic tiers. By the time HOLC stopped accepting applications in June 1936, it had processed applications covering roughly one-sixth of all urban home mortgage debt in the country.
The Residential Security Maps and Redlining
Between 1935 and 1940, HOLC staff worked with local lenders, developers, and appraisers to produce “Residential Security” maps for more than 200 cities. Each neighborhood received a letter grade and a color:
- Type A, green, “Best,” meaning the safest areas for mortgage investment, generally newer neighborhoods with modern housing.
- Type B, blue, “Still Desirable,” older or less exclusive but solid.
- Type C, yellow, “Definitely Declining,” with aging buildings, mixed uses, or shifting demographics.
- Type D, red, “Hazardous,” the highest-risk grade, often older housing with low values.
The grading went beyond bricks and mortar. Appraisers explicitly considered the race and ethnicity of residents. The presence of African Americans, immigrants, or Jewish families was treated as a threat to property values, sometimes described in appraisal narratives as “infiltration.” Minority neighborhoods dropped almost automatically into the lowest grades regardless of the condition of the housing.
The practice of drawing red lines around neighborhoods deemed too risky for lending, later called “redlining,” did not stay inside HOLC. The maps and the assumptions behind them shaped the underwriting of the Federal Housing Administration and private banks for decades, cutting minority neighborhoods off from the mortgage credit that built household wealth for everyone else.
How the Loans Performed
HOLC ultimately funded 1,017,821 mortgages. Performance was rough at first. By June 1936, when lending ended, about 400,000 accounts were already in default and another 230,000 were delinquent.3National Bureau of Economic Research. Financial Liquidation of the Home Owners’ Loan Corporation
Even so, roughly 80 percent of borrowers eventually kept their homes. Wartime recovery mattered: 90 percent of HOLC’s foreclosures were completed before the summer of 1940, and borrowers who survived that stretch benefited from rising incomes and home values in the 1940s.3National Bureau of Economic Research.

On the government’s books, HOLC finished slightly ahead. Against $352 million in gross income above expenses, it absorbed $338 million in losses, largely on foreclosed properties resold at a loss, for a net surplus of $14 million.3National Bureau of Economic Research.

Wind-Down
HOLC stopped making new loans in June 1936 and spent the next 15 years managing what it already held. It encouraged borrowers to prepay, sold active accounts to private buyers (mostly savings and loan associations and banks), and disposed of foreclosed property. Operations effectively ended by mid-1951, and the agency was formally terminated in February 1954.3National Bureau of Economic Research. Financial Liquidation of the Home Owners’ Loan Corporation
What HOLC Left Behind in Modern Mortgages
The most durable thing HOLC created was the loan itself. Before the 1930s, buying a home meant a large down payment and a balloon note due within a decade, a structure that worked in good times and collapsed in bad ones. The long-term, fully amortized loan HOLC popularized, with equal monthly payments covering both principal and interest, became the model the Federal Housing Administration adopted in 1934 and the conventional market followed after that. Congress reinforced the shift by creating Fannie Mae in 1938 to buy the longer loans from banks and keep credit flowing. Between 1945 and 1965, the U.S. homeownership rate rose by roughly 20 percentage points.
Laws That Later Targeted Redlining
The lending patterns HOLC’s maps helped normalize stayed legal for decades. Three federal statutes eventually addressed them, though none reversed the wealth gaps that had already formed.
The Fair Housing Act of 1968 made it illegal to refuse to sell, rent, or finance housing based on race, color, religion, sex, familial status, or national origin, and it barred discriminatory advertising and misrepresentations about housing availability.4Office of the Law Revision Counsel. United States Code Title 42 Section 3604 – Discrimination in the Sale or Rental of Housing
The Home Mortgage Disclosure Act of 1975 attacked the transparency problem, requiring lenders to disclose where they were making loans so regulators and the public could identify discriminatory patterns.5Office of the Law Revision Counsel. United States Code Title 12 Section 2801 – Congressional Findings and Declaration of Purpose
The Community Reinvestment Act of 1977 went further, establishing that banks have an affirmative obligation to meet the credit needs of the entire communities they serve, with federal regulators directed to evaluate that record during examinations.6Office of the Law Revision Counsel.

What The Maps Still Predict
Eight decades after HOLC appraisers finished their work, the grades they assigned still track economic outcomes. About 74 percent of neighborhoods graded “Hazardous” in the 1930s remain low-to-moderate income today. Nearly 64 percent of those same areas are now majority-minority. Cities where the old red zones have stayed predominantly minority show greater economic inequality than cities where neighborhood demographics shifted.
The mechanism is straightforward. Restricted lending held down home values in red-lined neighborhoods, which prevented residents from building the home equity that is the primary source of household wealth for most Americans. Where values eventually did rise, the shift sometimes brought gentrification and displaced long-time residents. The correlation between 1930s HOLC grades and modern poverty rates is one of the clearest surviving records of how a government risk-assessment program shaped the economic path of American communities for the better part of a century.
